Re: Processing IDREFS attributes

xsl idrefs
Well, I think the folks who wrote the specs thought you'd pass one IDREF 
at a time, rather than bunches of them. Also, I come from the school that 
keeps each function as atomic as possible, so I'd rather have tokenize and 
id be separate functions, since I'll undoubtedly use tokenize outside of 
id someday.

Re:  Processing IDREFS attributes






thanks,

that was where I was going, but I'm surprised that a function was provided 

to track down IDs but not one to pull apart IDREFS, or build that tokenize 

functionality into the id() function itself.

I'm slowly building a list of reasons to move on to XLST 2, just lazy at 
the moment I guess ;-)
